It has 8 clips around the perimeter. Just keep at it and it'll come out. It may or may not come out with the membrane contacts. Mine did not. The membrane simply lifts out.<a href="https://flic.kr/p/2rKPDyJ" target="_blank"><img src="https://live.staticflickr.com/65535/54973517702_b500fafd5e_z.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>You need to clean the PCB contacts (gold) and the membrane contacts (black). I used IPA.<a href="https://flic.kr/p/2rKUdZx" target="_blank"><img src="https://live.staticflickr.com/65535/54974410601_3af0c60f73_z.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a><a href="https://flic.kr/p/2rKV6ik" target="_blank"><img src="https://live.staticflickr.com/65535/54974579833_717ceb5893_z.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>To reassemble, just go in reverse. I lay the membrane in, then drop in the inner PCB. I go all the way around the PCB and make sure all 8 snaps are locked in. Then I drop the smaller PCB on top, making sure the pegs are lined up so the interboard connector goes in correctly.When you put the back cover on, be mindful of all the pins on the smaller PCB. If it doesn't go on easily, check for bent pins.</blockquote>
